Six reasons Illinois businesses choose ASI
1
Response within hours, not days
When your system has a problem, you talk to our Des Plaines team — not a national call center. We respond within hours to any issue.
2

Four decades under the same commitment: our family's name is on every installation, so quality and follow-up are personal.
3
Illinois-licensed and code-fluent
Licensed security contractor with deep knowledge of Illinois building codes, AHJ requirements, and local permitting.
4
Bank-grade expertise
600+ banks and 1,000+ ATM projects. If we meet the security standards of financial institutions, imagine what we do for your business.
5
A single source for everything
Burglary, fire, video, access control, environmental monitoring, and 24/7 monitoring — designed, installed, and serviced by one team.
6
UL-Listed fire & monitoring
UL-Listed fire alarm provider and UL-Listed central station monitoring based in Illinois. Bosch Authorized Security Dealer.
Financial institution security
Trusted where security standards are highest
Banks don't take chances on security contractors. Every bank project means vault and safe alarms, ATM protection, hold-up systems, video surveillance, access control, and compliance requirements that leave no room for error.
ASI has completed more than 600 bank projects and over 1,000 ATM installations across Illinois — a level of financial-sector experience few regional contractors can claim. That same discipline goes into every dispensary, nursing home, warehouse, and office we protect.
